Applications
Common use of the 1048 is to simulate a transducer or measure the current flow in a transducer loop. The 1048 can be used to check a 4 to 20 mA system in either source or measure modes of operation, with the 24 V compliance voltage powering the loop when current source mode is selected. In the source mode, the 1048 may be used to calibrate meters, thermocouple indicators, data loggers, for signal injection, semiconductor characterisation, or as a backing off source. In the measure mode, the 1048 may be used in the same way as a digital multimeter, checking DC voltages and current over 3 ranges with excellent resolution and accuracy.
